Dab tsi yog qhov tseem ceeb ntawm kev siv thiab kev ua haujlwm ntawm ferrosilicon

Ferrosilicon yog siv dav hauv kev lag luam hlau thiab hlau, kev lag luam casting thiab lwm yam kev lag luam. Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steel. Hauv steelmaking, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation. Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, ua kom cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm cov hlau transformer.

Ferrosilicon ua raws li deoxidizer, alloying tus neeg sawv cev thiab txo tus neeg sawv cev. Lub luag haujlwm ntawm silicon manganese yog deoxidizing tus neeg sawv cev, tus neeg sawv cev alloying thiab desulfurizing tus neeg sawv cev. Silicon tuaj yeem txhim kho elasticity thiab permeability ntawm hlau. Manganese tuaj yeem txo qhov brittleness ntawm qhov tawv nqaij, txhim kho kev kho cua sov ntawm qhov tawv nqaij, thiab ua kom lub zog, hardness thiab hnav tsis kam ntawm qhov tawv. Silicon-manganese alloys tuaj yeem deoxidize thiab tuaj yeem ua rau cov ntsiab lus manganese hauv cov hlau tiav thiab ua kom lub zog ntawm cov hlau. Yog li ntawd, qhov kev faib ua feem ntawm silicon-manganese alloy siv los ua deoxidizer yog maj mam siab dua li ntawm ferrosilicon. Raws li cov lus hais mus, "koj tsis tuaj yeem ua hlau tsis muaj manganese." Tam sim no, lub luag haujlwm ntawm manganese hauv cov txheej txheem steel tsis tuaj yeem hloov los ntawm lwm cov ntsiab lus.
